Effect of Rotablator on Balloon Resistant Calcified Coronary Lesion

Effect of Rotational Atherectomy on Balloon-resistant Calcified Coronary Lesion the During a Long-term Follow-up Study

The optimal treatment of calcified coronary lesion remained to be elucidated. A Prospective, randomized controlled trial was perform to explore the immediate effect and long-term outcome of rotational atherectomy in patients with balloon resistant coronary lesion.

The inclusion criteria included patients presenting drug-resistant angina pectoris who underwent balloon resistant angioplasty.

The exclusion criteria included:

1. Acute myocardial infarction within the 28 days;
2. Intolerance to aspirin, clopidogrel, contrast media, or statins;
3. Angiographic visible thrombus, or dissection;
4. Left ventricular ejection fraction (LVEF)<35%;
5. Any type of cancer
6. Hemorrhagic stroke

Inclusion Criteria:

• Drug-resistant angina pectoris
• Balloon resistant and angiographic calcified coronary lesion

Exclusion Criteria:

• Acute myocardial infarction within 28 days;
• Intolerance to aspirin, clopidogrel, contrast media, or statins;
• Angiographic visible thrombus, dissection;
• LVEF <35%;
• Any type of cancer;
• Hemorrhagic stroke
